고초균에 의한 비지 발효물을 첨가한 쿠키의 품질특성 연구
류미진,김혁일,이삼빈,Ryu, Mi-Jin,Kim, Hyuk-Il,Lee, Sam-Pin 한국식품영양과학회 2007 한국식품영양과학회지 Vol.36 No.8
재래청국장에서 분리된 Bacillus subtilis GT-D균주를 이용하여 생비지에 탈지대두미세분말(DSF), 뽕잎, 클로렐라 및 녹차를 첨가하여 비지발효물을 제조하였다. 비지발효물에서는 생비지에 비하여 점질물이 생성되면서 식이섬유 함량이 6배 정도 증가되었으며, tyrosine 함량이 크게 증가되었다. 부원료를 첨가한 비지발효물은 protease, amylase 및 혈전분해효소 활성이 크게 증가되었으며, 풍미 개선 효과도 나타났다. 또한 비지발효물을 첨가하여 제조한 쿠키의 색도 측정 결과 첨가하지 않은 대조군에 비하여 유의적인 차이는 없었으나 대조군이 69.45로 다소 밝게 나타났다. 쿠키의 퍼짐성은 부원료를 첨가하지 않은 비지발효물이 섞인 쿠키에서 9.07로 가장 높았으며 부원료를 첨가한 비지발효물로 제조한 쿠키에서는 다소 낮게 나타났다. 쿠키의 경도는 비지발효물이 첨가되지 않은 대조군에서 8,975 g으로 가장 높게 나타났고, 부원료 첨가 비지발효물로 제조한 쿠키에서는 경도가 유의적으로 낮게 나타났다. 특히, 클로렐라 함유 비지발효물로 제조한 쿠키의 경도가 3,618 g으로 가장 낮게 나타내었으며, 가장 높은 바삭거림을 보였다. 쿠키의 관능검사평가에서는 부원료를 첨가하지 않은 비지발효물로 제조된 쿠키의 선호도가 가장 높았으며, 뽕잎과 클로렐라 함유 비지발효물 순으로 나타났다. Soymilk cake (SMC) fortified with defatted soy flour was fermented by a novel Bacillus subtilis GT-D in the solid-state fermentation with chlorella, mulberry leaves or green tea as food ingredient. The fermentation of SMC resulted in higher content of tyrosine and higher activities of protease, amylase and fibrinolytic enzymes. Fermented SMC including mucilage indicated six-fold higher content of dietary fiber compared to that of non-fermented SMC. The SMC fermented without additional ingredient allowed the highest spread ratio and width of cookies. Cookies prepared without SMC showed the lowest value of spread ratio and width compared to those of fermented SMC. In addition, these cookies showed the highest hardness value of 8,975 g, and thickness value of 5.97 and slightly higher bright color. Cookies fortified with SMC fermented with chlorella or mulberry leaves showed higher sensory evaluation value. Fortification of SMC fermented without additional ingredient resulted in the highest preference in the sensory evaluation of cookies.

자생 산수국(Hydrangea serrata)의 발근에 미치는 IBA와 NAA의 영향
류미진(Mi-Jin Ryu),박병모(Byoung-Mo Park),배종향(Jong Hyang Bae) (사)한국생물환경조절학회 2010 생물환경조절학회지 Vol.19 No.4
자생 산수국의 대량번식을 위하여 삽목에 적합한 생장조절물질의 종류 및 농도와 침지시간이 삽목에 미치는 영향을 조사하였다. 자생 산수국의 숙지 삽목시 생장조절물질인 IBA와 NAA를 저농도(10~250㎎ㆍL?¹) 및 고농도(500~3,000㎎ㆍL?¹)로 침지시간을 각각 다르게 처리하여 삽목 한 후 42일(6주)째 발근율, 발근수, 근장, 엽장, 엽폭를 조사하였다. IBA처리의 경우 발근수, 근장, 엽장, 엽폭은 저농도(50~250㎎ㆍL?¹)일 때 우수하였다. 그 중 IBA 50㎎ㆍL?¹ 3시간 침지처리구에서 근수가 90.55개로 가장 좋았으며, IBA 10㎎ㆍL?¹일때 는 매우 저조하였으므로 산수국의 대량번식에는 효과를 주지 못하는 것으로 판단되었다. 또한 NAA 처리에서는 NAA 1000㎎ㆍL?¹ 5초 침지, 2000㎎ㆍL?¹ 3초 침지, 3000㎎ㆍL?¹ 10초 침지 일 때 발근율 100%를 보였으나 발근율에 비해 발근수는 오히려 감소되는 것을 볼 수 있었으며, NAA는 저농도(10~250㎎ㆍL?¹)보다 고농도(1,000~3000㎎ㆍL?¹)일 때 효과가 높았으며 고농도 중 NAA 2,000㎎ㆍL?¹ 5초 침지일 때는 발근수가 105.45개로 가장 많은 발근수가 나타났다. NAA의 고농도처리에서는 농도가 높고, 순간침지는 짧을수록 효과가 가장 높은 것을 볼 수 있었다. 따라서 자생 산수국의 대량번식을 위한 삽목번식에 적합한 생장조절물질은 NAA보다 IBA 저동도(50~250㎎ㆍL?¹)일 때 발근율 및 효과가 높았다. 이와 같이 자생 산수국의 대량번식에 적합한 생장조절 물질은 IBA가 NAA에 비해 발근율 및 발근수 등이 좋았으며, IBA 50㎎ㆍL?¹ 3시간이 삽목에 가장 효과적이었다. This study was conducted to find out the appropriate type and concentration of plant growth regulator for mass production of wild type Hydrangea serrata. And the optimal soaking time for rooting of the cuttings was also investigated. When the cuttings of Hydrangea serrata were cultivated for 6 weeks after immersing in 50 ㎎ㆍL?¹ of IBA for 3 hrs, the number of roots was 90.6. However the number was significantly decreased when the cuttings were treated with 10 ㎎ㆍL?¹ of IBA. The rooting ratio was 100% when the cuttings was immersed in 1,000, 2000 and 3000 ㎎ㆍL?¹ of NAA solution for 5, 3 and 10 sec., respectively. Despite the perfect rooting, the number of roots was decreased. The number of roots was 105.5 when the cuttings were treated in 2,000 ㎎ㆍL?¹ of NAA for 5 sec., which was the highest number in NAA treatment. Overall, the rooting ratio and growth was better when the cutting was treated with low concentration of IBA (50~250 ㎎ㆍL?¹) than the treatment of NAA. And the most appropriate concentration and time fot the treatment of IBA was 50㎎ㆍL?¹ and 3 hrs, respectively.

Gallbladder tuberculosis is an extremely rare disease that is rarely reported in the literature. Arriving at the correct diagnosis of gallbladder tuberculosis is difficult, and it is usually made by histopathologic examination after cholecystectomy. However, due to the low sensitivity of acid-fast stain and culture result, diagnosing gallbladder tuberculosis is still demanding even after tissue acquisition. To overcome this problem, tuberculosis-polymerase chain reaction (TB-PCR) is performed on the resected specimen, which has high sensitivity and specificity. A 70-year-old female who had previously undergone total gastrectomy for advanced gastric cancer was admitted with right upper quadrant pain. Abdominal ultrasonography and computed tomography revealed acute cholecystitis without gallstones or sludge. She underwent cholecystectomy and the histopathologic finding of the specimen showed chronic active cholecystitis without gallstones or sludge. Because she was suspected to have pulmonary tuberculosis, TB-PCR was also performed on the resected gallbladder. TB-PCR showed positive reaction for Mycobacterium tuberculosis and we could diagnose it as gallbladder tuberculosis. Herein, we present a case of gallbladder tuberculosis diagnosed by TB-PCR from resected gallbladder. (Korean J Gastroenterol 2014;63:51-55)

Basaloid squamous cell carcinoma is a rare and aggressive variant of squamous cell carcinoma, which mostly occurs in the upper aerodigestive tracts. Basaloid squamous cell carcinoma also typically arises in the anal canal, but is extremely rare in the lower gastrointestinal tract. A 70-year-old man presented with loose stool and intermittent hematochezia 2 months ago. Colonoscopy showed an ulceroinfiltrative mass on the rectosigmoid colon from 16 cm to 18 cm above the anal verge. Conventional colonoscope could not pass through the lesion but it was possible with pediatric colonoscope. Abdominal CT scan showed 1.6 cm sized wall thickening with circumferential luminal narrowing in the rectosigmoid colon and multiple ill-defined low density masses in both lobes of the liver. Therefore, colon cancer with liver metastasis was suspected. However, basaloid cells were noted on histologic examination, and they were weakly positive for synaptophysin on immunohistochemical study. After palliative lower anterior resection, histologic examination of the resected specimen revealed basaloid differentiation with keratin pearls, and tumor cells were positively stained with high molecular weighted cytokeratin (34BE12) and CK 5/6. Thus, the patient was finally diagnosed with basaloid squamous cell carcinoma of rectosigmoid colon with distant metastases. (Korean J Gastroenterol 2013;62:375-378)
